In 1865, Abraham Lincoln ran for reelection on the Republican Party ticket. His running mate was Andrew Johnson, a senator from Tennessee. Although Johnson was from a southern state, he supported the Union in the Civil War. At Lincoln’s Second Inaugural, the newly elected vice president made a memorable appearance. Before Lincoln delivered his great address, Johnson, who was possibly drunk, gave an incoherent, rambling speech that lasted almost an hour. (Library of Congress)
